Technical Summary

Sampling was conducted from the vessel Svetlomor 2 by personnel from AmC, the Ministry of Ecology and Natural Resources (MENR) and SOCAR. Sediment samples for physical and chemical analysis consisted of 2 replicates, while 3 replicates were taken for biological analyses. Analyses were carried out at AmC Caspian Environmental Laboratory.

The sediments around East Azeri were very poorly sorted with generally good agreement between replicate samples.Variation between metal concentrations was low.

Metal and hydrocarbon concentrations were, with the exception of Ba and Cd, within the range of baseline conditions for the ACG contract area, and in many instances were lower in 2010 than in 2008.

The condition of the macrobenthic community throughout the survey area was, in 2010, better than in 2008, and was closer to the original baseline conditions. There was no evidence that any physical or chemical parameter was associated with impaired community structure or function, although it was clear that the dominant taxonomic groups were more diverse and abundant in coarser sediments.

Specifically, the results of the 2010 survey show no evidence of sustained impact as a result of continuing platform drilling and production operations; there has (with the possible exception of Cd) been no evidence of direct contamination, and the diversity, abundance and biomass of the macrobenthic community has improved since 2008.
